[0002] Welded steel beams are a type of composite beam. Commonly used welded steel beams are I-shaped and box-shaped sections composed of upper and lower flanges and webs. The latter is more material-intensive and has a more complicated manufacturing process, but it has greater bending and torsional stiffness and is suitable for situations with high requirements for lateral loads and torsional resistance or where beam height is limited.

[0003] The required dimensions of the steel beams vary at different locations, and protective structures are typically installed on the welding table to prevent sparks from injuring welders during the welding process.

[0004] Traditional welding protection structures are generally fixed on the welding table and cannot be flexibly adjusted according to changes in the welding position. Furthermore, if a complete protective cover is damaged, it is inconvenient to replace it.

[0005] Therefore, it is necessary to provide a steel beam welding protection device to solve the above-mentioned technical problems. Utility Model Content
